Commit Message

Moudy Ho March 17, 2022, 2:39 p.m. UTC 
In order to allow multiple modules to operate MUTEX hardware through
a common interfrace, a flexible index "mtk_mutex_table_index" needs to
be added to replace original component ID so that like DDP and MDP
can add their own MUTEX table settings independently.

In addition, 4 generic interface "mtk_mutex_set_mod", "mtk_mutex_set_sof",
"mtk_mutex_clear_mod" and "mtk_mutex_clear_sof" have been added, which is
expected to replace the "mtk_mutex_add_comp" and "mtk_mutex_remove_comp"
pair originally dedicated to DDP in the future.

tab is always 0 in this series, so remove this.

Without tab, this struct is not necessary.

Since single mode SOF is the only type used in the 8183 MDP3, the
switch case should be removed and represented in another way. Perhaps
we can import a new SOF tables to integrate the requirement of
different modules.
